simplify t^2cos(2t+30)u(t)

Solution

simplify

t^{2} cos (2 t + 3 0^{\circ}) u (t)

Solution

t^{3} u cos (2 t + 3 0^{\circ})

Solution steps

t^{2} cos (2 t + 3 0^{\circ}) u (t)

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

t^{2} t = t^{2 + 1}

= cos (2 t + 3 0^{\circ}) u t^{2 + 1}

Add the numbers:

2 + 1 = 3

= cos (2 t + 3 0^{\circ}) u t^{3}
